Prince William was on hand this week to give a morale boost to Royal Navy submariners, nearly a week after HMS Astute ran aground off the Isle of Skye.
The 28-year old is the Commodore-in-Chief, Submarines and trained on the vessels as past of a two-month attachment to the Navy in 2008.
Presenting long-service awards at the Faslane naval base on the river Clyde, the Prince was seen joking and laughing with servicemen.
Chief Petty Officer Stephen Irvine, one of the honourees, said: "I felt really privileged to be one of the first to get the award, and from our future king."
Meanwhile, Prince Charles has joked about his son's new job as an RAF search and rescue pilot during a lunch with Welsh sheep farmers.
"Bearing in mind the sheep's unerring desire to commit suicide, it really is a miracle anything ever arrives on anyone's plate.
"I spend my life trying to extract sheep stuck in fences or upside down somewhere or other, or marooned on rock ledges or at the bottom of cliffs as the tide comes in," he said.
"I dare say at this moment my eldest son may well be rescuing one stuck halfway up a mountain - in between other damsels in distress," he added referring to William's new life in North Wales with girlfriend Kate Middleton.
